True North Canine

True North Canine is a professional dog training business run by Patrick Mullooly, a U.S. Marine Corps veteran. The company offers board and train programs, private in-home lessons, virtual coaching and behavior modification for aggression, reactivity and fear. Behavior work is described as the company's specialty.

Programs include coaching for owners so progress continues at home, and graduates can join weekly group lessons. Private lessons take place in the home across the Dallas-Fort Worth area, and board and train dogs live with the trainer for three, four or six weeks. The business is at 608 W Main St in Celina, and it lists Celina, Prosper, Frisco and McKinney among the communities it serves.
